- the curing degree of the partially cured adhesive is between 50% and 90%. The curing degree of the partially cured adhesive would affect the adhesion of the adhesive layer 11 .
- the adhesive layer 11 formed by curing of the cured partially cured adhesive can hardly adhere to the first product housing 10 a and the second product housing 10 b ;
- the curing degree of the partially cured adhesive is too high, after applying the protective glue on the partially cured adhesive, the adhesion between the protective layer 12 formed by curing the protective glue and the partially cured adhesive is also hardly adhering to the adhesive layer 11 since the protective glue is difficult to infiltrate into the interior of the partially cured adhesive glue.

Finally test the infiltration, shear strength, and cross shear strength of the control sample 1 and the sample 1 after treated with oleic acid treatment. The test results are shown in Table 1.
- both the shearing ability and the cross shearing ability were greatly attenuated compared to the control samples before the oleic acid treatment, which means that the interface of the adhesive layer 11 of the control sample 1 was damaged by oleic acid, which greatly attenuated the adhesive strength of the adhesive layer 11 of the control sample 1.
- the shearing ability and cross shearing ability of sample 1 after oleic acid treatment are pretty much comparable to those of sample 1 before oleic acid treatment. So, the protective layer 12 in the sample 1 can keep the adhesive layer 11 in good adhesion strength.

- the infiltration depth of the oleic acid into sample 3 is about half of the infiltration depth for a full penetration, and sample 3 after the oleic acid resistance has better ejection strength.
- Sample 3 only partially infiltrated in the oleic acid testing, while in the sample 3 the sebum testing and the sweat testing were not infiltrated. It should be noted that the zero infiltration depth herein only means that the infiltration cannot be observed by eyes.
- the adhesive layer 11 of the control sample 3 was infiltrated in all three tests, particularly the oleic acid which infiltrates all the way down to the bottom, which is, infiltrating from an outer surface to an inner surface of the adhesive layer 11 . Therefore, the testing results show that the adhesive layer 11 provided with the protective layer 12 can effectively isolate external and human contaminations.
- embodiments of the present disclosure provide a product for preventing the deterioration of an adhesive layer and a method for manufacturing the product.
- the protective layer could prevent the adhesive layer from erosion of external and human contaminants, which deteriorates the adhesive layer. Without deterioration, the adhesive layer can be healthy to stably bond the first product housing and the second product housing.
- the protective layer would not affect the performance of the product.

It can be seen from the above that an obvious color change of the infiltration of the control sample 1 after being treated with oleic acid treatment, from white to yellow. The sample 1 showed color retention in white. That is, the
